3M Company Announces Pricing of Its Cash Tender Offers

ST. PAUL, Minn.–(BUSINESS WIRE)–3M Company (“3M”) (NYSE: MMM) today announced the pricing of its
previously announced tender offers to purchase for cash up to
$400,000,000 aggregate principal amount of its 5.70 percent notes due
2037 and 6 ⅜ percent debentures due 2028 (each, an “offer,” and
collectively, the “offers”). The terms and conditions of the offers are
set forth in 3M’s offer to purchase dated Sept. 21, 2017 (the “offer to
purchase”). Capitalized terms used but not defined herein have the
meanings ascribed to them in the offer to purchase.

Holders (as defined below) of each series of notes who validly tendered
and did not validly withdraw in the offers (each series, a “series of
notes,” and such notes, collectively, the “notes”) at or prior to 5
p.m., New York City time, on Oct. 4, 2017 (the “early tender deadline”),
as reported by the tender agent and information agent, and whose notes
were accepted for purchase by 3M, are eligible to receive the total
consideration set forth in the column “total consideration” in the table
below. Holders of notes who validly tender and do not validly withdraw
in the offers after the early tender deadline and at or prior to the
expiration date (as defined below), as reported by the tender agent and
information agent, and whose notes are accepted for purchase by 3M, will
be eligible to receive the tender consideration set forth in the column
“tender consideration” in the table below.

Subject to the terms and conditions of the offers, holders or beneficial
owners (“holders”) of notes who validly tendered and did not validly
withdraw their notes at or prior to the early tender deadline, and whose
notes are accepted for purchase by 3M, are eligible to receive
consideration, per $1,000 principal amount, equal to the applicable
total consideration for such series of notes. The total consideration
has been determined in the manner described in the offer to purchase by
reference to the applicable fixed spread for such series of notes set
forth in the column entitled “fixed spread” in the table above, over the
applicable yield based on the bid side price of the U.S. Treasury
Security set forth for such series of notes in the column entitled
“reference security” in the table above, as calculated by the dealer
manager (as defined below) at 11 a.m., New York City Time, on Oct. 5,
2017. The total consideration includes an early tender premium equal
to $50 per $1,000 principal amount of such series of notes accepted for
purchase (the “early tender premium”). Subject to the terms and
conditions of the offers, holders who validly tender and do not validly
withdraw their notes after the early tender deadline and at or prior to
the expiration date, and whose notes are accepted for purchase by 3M,
are eligible to receive consideration, per $1,000 principal amount,
equal to the tender consideration for such series of notes. The tender
consideration is equal to the applicable total consideration less the
applicable early tender premium for such series of notes.

The withdrawal deadline of 5 p.m., New York City Time, on Oct. 4,
2017, has passed and the notes tendered pursuant to the offers may no
longer validly be withdrawn, subject to applicable law.

The offers will expire at midnight, New York City time, at the end of
Oct. 19, 2017, unless extended or earlier terminated (such time and
date, as the same may be extended with respect to one or more series of
notes, the “expiration date”).

3M’s obligation to accept for purchase, and to pay for, notes that are
validly tendered and not validly withdrawn pursuant to the offers is
conditioned on the satisfaction or waiver by 3M of a number of
conditions. 3M may amend, extend or, subject to certain conditions and
applicable law, terminate any or all of the offers at any time in its
sole discretion.

manager”) and D.F. King & Co., Inc. is acting as the tender agent and
information agent for the offers. Requests for documents may be directed
